Several studies in animals have found similar results, noting that certain compounds and polyphenols extracted from grapes and grape juice could support the health of the gut microbiome ( 15, 16). Some research has found that grape juice might support the health of your digestive system.įor instance, a recent study showed that taking a grape powder supplement - equivalent to about 3.4 ounces (100 mL) of grape juice - could increase the diversity of your beneficial gut microbiome to promote digestive health ( 13, 14). Grape juice is also a great source of antioxidants, like resveratrol, a compound that can reduce inflammation and regulate immune cells ( 12). Getting enough vitamin C in your daily diet may reduce your susceptibility to illness and infection, including respiratory infections, like the common cold ( 10, 11). Vitamin C can enhance immune function by reducing oxidative stress and supporting the function of your immune cells ( 10). Many varieties of grape juice are enriched with the micronutrient vitamin C. Still, more high quality research is needed to better understand the juice’s effects on heart health. As such, it might help protect against heart disease ( 9). Similarly, a review reported that grape products, including grape juice, could significantly improve levels of total, LDL (bad), and HDL (good) cholesterol compared with a control. In a small study with 25 women, drinking white grape juice daily for 30 days increased levels of HDL (good) cholesterol by 16% and decreased belly fat ( 8). Thanks to its content of antioxidant compounds, several studies have found that grape juice could support heart health.Īccording to one review, the flavonoids found in Concord grape juice could help lower several risk factors for heart disease, including ( 7): For example, it may promote the health of your heart, immune system, and digestive tract. Grape juice has been associated with several health benefits. Grape juice is high in carbs, but it also contains a good amount of vitamin C, manganese, and antioxidants in each serving. These are plant compounds that act as antioxidants to protect against oxidative stress and inflammation ( 6). What’s more, grape juice contains several flavonoids and polyphenols. Grape juice is also rich in manganese, a mineral involved in bone formation and the production of certain neurotransmitters in your brain ( 5).

This nutrient is essential for immune function and skin health ( 4).
Many types of grape juice contain added ascorbic acid, also known as vitamin C.
One cup (237 mL) of unsweetened purple grape juice contains the following nutrients ( 3): Though grape juice is high in carbs and natural sugar, it’s also a good source of several nutrients, including vitamin C and manganese. They differ depending on whether they’re sweetened, the types of grapes used, and whether they’re made from concentrate, a blend of fruits, or 100% fruit juice. There are several types of grape juice available. Added sugar can be found listed on the ingredients label. Sweetened grape juice contains added sugars, like high fructose corn syrup. Grape juice may be sweetened or unsweetened. Grape juice is also featured in many juice cocktails, some of which contain a blend of several types of fruit. That means that most of the water has been removed, resulting in a more concentrated product ( 2). Other varieties are labeled as juice from concentrate. Some grape juice is labeled as 100% juice, meaning that all the ingredients are extracted from fruits or vegetables ( 2). You can also purchase white grape juice, which is made from green-skinned grapes and boasts a slightly sweeter taste. It features a dark color and is usually made from Concord grapes. Purple grape juice is the most commonly available commercial variety. They differ in nutritional content and which specific grapes they’re made from.
